A new benzimidazolium - based chiral fluororeceptor 1 has been designed and synthesized. The open cleft of 1 is found to recognize fumarate selectively over maleate in CH3CN by exhibiting greater change in emission. In comparison, the achiral receptor 2, under similar condition, shows poor selectivity in the recognition of fumarate over maleate. Interaction studies were performed by 1H NMR, fluorescence and UV-vis spectroscopic methods. © 2011 Bentham Science Publishers Ltd.

Selective Sensing of Fumarate Over Maleate by Benzimidazolium – Based Fluororeceptors

Mini-Reviews in Organic Chemistry

A new ortho-phenylenediamine-based fluorescent cleft 1 has been designed and synthesized. The open cleft of 1 selectively recognizes tetrabutylammonium dihydrogen phosphate in CH3CN by exhibiting a significant decrease in the emission of anthracene. The interactions of 1 are also investigated in aq CH3OH where no measurable change in the emission is observed for tetrabutylammonium dihydrogen phosphate, although sodium salts of phosphate, hydrogen phosphate, and dihydrogen phosphate exhibit moderate changes. Tetrabutylammonium hydrogen sulfate is sensed effectively in aq CH3OH. The anion binding properties of 1 were evaluated by 1H NMR, UV-vis, and fluorescence spectroscopic methods. © 2009 Elsevier Ltd.
